    摘要: A cutting apparatus to cut a tow includes a tow support, first blade, and tow support deflector. The tow support supports the tow. The first blade cuts the tow. The tow support deflector is disposed in cooperative alignment with the first blade to exert a deflecting force upon the tow support. The deflecting force substantially prevents the first blade from striking the tow support.

    摘要: A multiple head tape placement system includes several tape heads. Each tape head includes: a guide chute and a compaction roller for delivering a composite material to a mandrel. A backing is removed from the composite tape material before it reaches the compaction roller. Each tape head also includes a material cutter disposed to cut the composite tape material after the backing is removed and before the material reaches the compaction roller. The material cutter includes a curved blade with a convex cutting surface and a flat blade that contacts the curved blade in at most two contact points along a cutting edge of the flat blade as the flat blade moves vertically up and down past the curved blade with a horizontal rocking motion. The curved blade and the flat blade cut the composite tape material simultaneously in two opposing directions without laterally misaligning the composite tape material.
